gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1
```
* Confirm a correct key import and proceed to verify the downloaded file with the help of the signature file:
`$ wget https://download.electrum.org/3.3.4/Electrum-3.3.4.tar.gz.asc`
`$ gpg --verify Electrum-3.3.4.tar.gz.asc`
```

## Electrum Personal Server
Follow Stadicus`s guide:
https://github.com/Stadicus/RaspiBolt/blob/master/raspibolt_64_electrum.md
some permissions I needed to fix:
>ssh admin@Raspibolt
>sudo su - bitcoin
>ls -la
`drwx------ 6 bitcoin bitcoin 4096 Jan 2 23:55 .local`
>chmod 755 .local
`drwxr-xr-x 6 bitcoin bitcoin 4096 Jan 2 23:55 .local`
monitor the log:
>tail -f /tmp/electrumpersonalserver.log
restrict Electrum to use your own EPS, point it to the LAN IP of your Raspibolt
>python3 run_electrum --oneserver --server [RaspiBolt.IP]:50002:s
